My research interests are primarily focused on innate immunity of the brain. In particular, the research objective of my laboratory is to elucidate mechanisms by which inflammatory episodes in the periphery elicit inflammatory response in the brain and alter its function.

My research interests are primarily focused on the immune-to-brain communication. In particular, the research objective of my laboratory is to elucidate mechanisms by which inflammatory episodes in the periphery alter brain function.
The immune system and the brain maintain intricate communication that plays an important role in both health and disease. For example, epidemiological evidence indicates that peripheral viral infections are comorbid factors in seizures. The putative mechanisms entail pathways by which inflammatory signals are relayed to the brain and lower seizure threshold. However, these pathways have not been defined. We have developed a preclinical murine model in which the peritoneal injection of a viral mimetic, polyinosinic-polycytidylic acid (PIC) robustly increases susceptibility to kainic acid (KA)-induced seizures. Subsequent studies have indicated that the principal mechanism entails dysregulation of glutamate homeostasis in hippocampal astrocytes and that this dysregulation is mediated by the activation of endogenous complement pathways.
